ui: split Phone simulator into Phone and TR Config pills

- Phone pill: STK menu, STATUS and polling and the subscribed-events list
  in one row, proactive command log full-width below (room for more
  elements)
- TR Config pill: response data injected into TERMINAL RESPONSEs;
  currently the PROVIDE LOCAL INFORMATION dictionary, structured as
  heading + body blocks for future proactive-command responses
- phoneSwitchSubtab() mirrors the other sub-tab switchers and sets help
  anchors stk-menu / pli-dict; switchTab('phone') always opens Phone
- refreshDynamicI18n renders only the visible phone panel
- help EN/RU section 6 regrouped (6.4 STATUS polling under Phone, 6.5
  TR Config response data), READMEs and AGENTS.md updated
- structural and behavioral tests (html.test.js, phone_tabs.test.js);
